健康和高产种薯的生产与病毒病的控制以及其他栽培措施,如减缓块茎的生理成熟密切相关。在1983/1984,1984/1985和1985/1986这3季,将品种Bonaerens La Ballenera MAA种株提早杀死薯秧。收获后,种薯堆放贮藏在大田中,然后评价种薯的发芽能力、生理成熟和块茎产量。结果表明,提早杀死薯秧既不影响种薯的上述性状变化,又不降低所收获种薯的品质。
The production of healthy and high-yielding seed tubers is closely linked to the control of viral diseases and other cultivation measures, such as slowing the physiological maturation of tubers. In the three seasons of 1983/1998, 1984/1985 and 1985/1986, potato seedlings of Bonaerens La Ballenera MAA variety were prematurely killed. After harvesting, the seed pots are stored in the field and then evaluated for germination capacity, physiological maturity and tuber yield. The results showed that the early killing of potato seedlings did not affect the above characteristics of seed tubers without reducing the quality of harvested seed.
